rust-agents

Rust strategic architect specializing in type-driven design, domain modeling, workspace architecture, and compile-time safety patterns. Use PROACTIVELY when starting projects, designing type hierarchies, making architectural decisions, or implementing state machines with typestate pattern.

Rust developer specializing in idiomatic code, ownership patterns, error handling, and daily feature implementation. Use PROACTIVELY for implementing features, writing business logic, and refactoring code.

Rust testing specialist focused on comprehensive test coverage with nextest and criterion, test infrastructure, and quality assurance. Use PROACTIVELY when adding new functionality that requires tests, investigating test failures, or setting up test infrastructure.

Rust performance optimization specialist specializing in macOS optimizations (sccache, XProtect), profiling with flamegraph, benchmarking with criterion, and build speed improvements. Use when performance concerns are mentioned, slow code identified, build times need optimization, or macOS-specific optimization needed.

Rust security and maintenance specialist focused on cargo-deny, dependency management, vulnerability scanning, and secure coding practices. MUST BE USED for unsafe code blocks, authentication, authorization, cryptography, or external input validation.

Rust code reviewer specializing in quality assurance, standards compliance, constructive feedback, and ensuring best practices. Use PROACTIVELY before committing code, after feature implementation, or when pull request review is needed.

Rust CI/CD and DevOps engineer specializing in GitHub Actions, cross-platform testing, code coverage, caching strategies, and efficient workflows. Use PROACTIVELY when setting up CI/CD pipelines, fixing failing workflows, or configuring automated testing.

Rust debugging and troubleshooting specialist focused on systematic error diagnosis, runtime debugging with LLDB/GDB, panic analysis, async debugging, memory issues, and production incident investigation. Use PROACTIVELY when encountering compilation errors, runtime panics, unexpected behavior, performance anomalies, or production issues.

Adversarial critic specializing in finding logical gaps, flawed assumptions, scalability limits, and missing edge cases in architectural designs, implementation proposals, and ideas. Use PROACTIVELY after architecture design, before committing to an approach, or when a user wants their idea stress-tested. Never writes code — only produces structured critique reports. Triggers on "review this design", "challenge assumptions", "find weak points", "devil's advocate", "stress test this idea", "what could go wrong", "critique this".

Spec-Driven Development agent. Use when the user wants to define a new feature, design a system, write requirements, create a PRD, prepare tasks for coding agents, or turn a vague idea into an actionable specification.

Rust team orchestrator managing agent teams for complex multi-phase development. Use when coordinating multiple agents for features, refactorings, or investigations requiring cross-agent collaboration.

Validate, format, and convert YAML/JSON files using fast-yaml (fy) tool. Triggers on: 'validate yaml', 'format yaml', 'lint yaml', 'check yaml syntax', 'convert yaml to json', 'convert json to yaml', 'yaml formatter', 'fix yaml formatting', 'json to yaml'. Supports bidirectional YAML ↔ JSON conversion, YAML 1.2.2 spec with parallel processing for batch operations.

Write, structure, and maintain high-quality technical documentation using mdBook. Use when creating or editing mdBook projects, writing Rust/software project documentation, structuring SUMMARY.md, drafting chapters, API references, tutorials, architecture docs, or any mdBook-related content. Triggers on "mdbook", "documentation", "write docs", "technical writing", "book.toml", "SUMMARY.md", "chapter", "tutorial", "API reference", "architecture doc", "user guide", or "developer guide".

Generate and improve README files for software projects. Triggers on: 'create readme', 'generate readme', 'write readme', 'improve readme', 'update readme', 'fix readme', 'readme for this project'. Supports Rust (libraries, CLI tools, services), TypeScript/JavaScript (npm packages), and Python (PyPI packages). Applies ecosystem-specific conventions: badges, installation sections, MSRV for Rust, feature flags documentation.

Handoff protocol for Rust multi-agent development system. Use when working as rust-architect, rust-developer, rust-testing-engineer, rust-performance-engineer, rust-security-maintenance, rust-code-reviewer, rust-cicd-devops, rust-debugger, or rust-critic. ALWAYS read on agent startup.

Prepare Rust project release with version bump, changelog update, and documentation refresh. Triggers on: 'prepare release', 'bump version', 'release patch', 'release minor', 'release major', 'version bump', 'create release'. Supports single-crate and workspace projects.

Orchestrate Rust development using agent teams with peer-to-peer communication. Use when: 'create rust team', 'start team development', 'launch agent team', 'team workflow', 'collaborative development'. Requires rust-agents plugin and CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1.

Spec-Driven Development workflow. Use when the user wants to create a specification, write requirements, design a feature, plan implementation, break work into tasks, or review spec quality. Also trigger when the user says 'I want to build X', 'let's spec this out', 'create a spec', 'write requirements', or asks to prepare work for a coding agent.
